I have been using FreeBSD since version 2.0.5 and during that time 
the serial callin ports have always been named ttyd?, callout ports cuaa?
and floppy drives fd0, fd1. The names are not new or changed.

I guess you could have created your own device files or renamed them choosing 
any name you want; but most people find it more convenient to stay with the 
defaults as other applications won't find them.

I think you may be confused with the serial driver names, sio? and the floppy
disk controller name fdc0; which as far as I can remember always have been and 
still are.
